    I have a big apology to make to Irv Howarth, which I need to explain-
    
    Bill Sellar asked a simple question.
    
    "As a beginning celestial navigator, I am wondering how much time and watch
    accuracy is actually required for practical navigation. Can we predict how
    many miles off one would be for every second of time error?"
    
    And I commented on the heavy weather the list was making of such a simple
    matter, adding-
    
    "Worst was Irv Howarth's contribution, in which he made a gross error, by a
    factor of 15! Well, anyone can make a mistake, but after it's been pointed
    out to him, he appears to be still defending it."
    
    That was quite unjustified, as the factor of 15 error had been made, not by
    Irv Howarth, but by Rick Emerson, in posting 6933.
    
    Irv must be wondering what he had done wrong, and I can only say "sorry" to
    him for making such a mistake.
    
    George.
